Coach Jim Harbaugh and general manager Trent Baalke are expected to attend. The only other pro day Harbaugh has attended thus far is that of Texas Christian quarterback Andy Dalton, who, like Kaepernick, is widely rated as second-round prospect. The Bee reported that another quarterback who falls into that category -- Iowa's Ricky Stanzi -- also has caught the 49ers' eye.

Nevada's pro day is March 27, but the 49ers apparently are eager to get a closer look at the rocket-armed Kaepernick, who is 6-foot-5 and 225 pounds.

A standout at both the Senior Bowl and the NFL Scouting Combine, Kaepernick is the only player in NCAA history to pass for more than 10,000 yards while rushing for more than 4,000. He capped his career by passing for more than 3,000 yards while completing nearly 65 percent of his passes during a 2010 season in which the Wolfpack finished 13-1.

The only 49ers quarterback under contract for next season is backup David Carr. The team is weighing whether or not to re-sign former No. 1 overall draft choice Alex Smith, who is a free agent.
